Abstract

A system and method for integrating a business transaction processing system, a process control system, and a laboratory system provides a computer integrated manufacturing environment. The manufacturing execution system receives work orders from the business transaction processing system and obtains enrichment data to enhance the work orders. The manufacturing execution system uses the enrichment data and rules contained in a plant model database to generate setpoints based on the received work orders. A subset of the work order data is provided to the laboratory system to direct sample testing. The setpoints include detailed information required by the process control system to manufacture the product specified by the work order. The setpoints are transmitted to the process control system for manufacture of the required materials. The manufacturing execution system collects the manufacturing data resulting from the execution in response to the work order by the process control system and processes this manufacturing data to provide summary information on manufacturing processes and to provide inventory information data. The manufacturing execution system also collects the results of sample testing from the laboratory system and links the sample result data to the manufacturing process summary information, and combines these two data sources to determine the final quality status for a lot of manufactured product. This data is then transmitted to the business transaction processing system so that business records may be maintained.
